mnans non CLEANING AND TURNING BAGS.

citizen, of the United States, residing at Dedham, in the county ofNorfolk and State of Massachusetts, have invented certain nfew or Bags;and I do herethe following to be a full, clear, description of theinvention, such as. will enable others skilled'in the a'rt'to which itappertains to make and .use the same.- I

- This invention relates to means for cleaning and turning bags.

The'object is to provide a device of simple construction which will dothe work of more-elaborate machines, which shall be efficient inperforming the turning operation, and whichwill then thoroughly cleanthe bag, the air having access to all portions of the latter while it isbeing held by suction in an expanded form against walls of screenlikeformation.

With these and other objects in view, the invention consists in thenovel construction hereinafter set forth and claimed, and illustrated inthe accompanying drawings, in which- Figure 1 is a view of theconstruction in side elevation, with parts in section. Figs. 2 and 3show details of the device.

In carrying out my invention, I employ .a tubular member 10 which hasconnection with an exhaust fan 15 mounted on any suitable supportingstructure 16. The duct constituting the dust outlet from the fan isshown at 17.

It is obvious that the member 10, which will be termed a suction pipe,may be 10- cated in any manner desired. but it is found convenient tohave it depend vertically, and

terminate at a convenient distance above the floor, so that an operatormay readily place the bags to be turned and cleaned, at the mouth of thepipe.

Especial importance is attached to the means for retaining the bag in asuitable position to be cleaned after it has been placed at the mouth ofthe pipe and turned by suction while the edges are being'held by theoperator against the edge of the pipe.

A cylindrical screen of suitable mesh is placed within pipe 10, andprovides an annular air space 18 between the two members.

. Specification of Letters Patent.

this air space having direct communication with a larger air chamber 19beyond the end of the screen, the latter being indicated .by the number20. In order to hold the screen suitably spaced from pipe 10, spacingmembers 21 are provided, of such character as to" admit of the freepassageof the air. It will be noticed that the suction is direct betweenall portions of the annular air space 18 and-the exhaust device.

In order that the screen may be removed for any purpose, as for instanceto permit the substitution of a screen of another size, tube 10 isprovided with a telescoping collar member 22 which is secured inposition by devices 23. This collar is madeto taper and is provided witha rolled edge 24:.

Screen member 20 is secured to collar 22. so that whenthe latter isremoved the screen may be withdrawn at the same time.

Itwill be observed that the main portion of pipe 10 is of uniform crosssection and that there are. no obstructions to engage the screen spacingmembers when they pass the mouth of the pipe.

The end portion 25 of screen 20 is of larger mesh and retains the bag,preventing it from. being drawn into the fan casing. Screens ofdifl'erent mesh and of difierent cross section may be employed.

The device contains no valves, nor any moving parts other than the fan,the latter operating continuously to produce constant suction suflicientfor the purpose, and for whipping the sides of the bag against thescreen. X

If the bag is right side out at the beginning, it is first turned, thencleaned, the cleaning operation beginning during the turning operation,and is then again turned to bring the bag to the right side. In theevent that the user has turned the bag in emptying it, the first turningin the machine leaves the bag right side out, and it is cleaned in thatposition, and while being turned.

. What I claim as new and desire to secure by Letters Patent, is:
